Nanoparticle-Mediated remediation of wastewater contaminants: An inclusive analysis of glyphosate, Congo red and methyl orange

New techniques in purification are called for because, currently pollutants found within the wastewater sources are known to have adverse effects of man health, agricultural productivity and industrial applications. The purpose of this research was to assess the efficiency of different synthesized NPs in the rteutal of glyphosate, Congo red and MO from aqueous solution using a glass column. To determine the concentration of these contaminants, two analytical techniques namely High-Performance Liquid Chromatography (HPLC) and UV–Visible spectrophotometry were used. The findings revealed that the community removal rates differed depending on nanoparticle type, treatment time and light intensity. Zinc oxide nanoparticles (ZONPs) were found to reduce the glyphosate concentration by 56.81 % under 100-watt light after 120 minutes. Iron oxide nanoparticles (IONPs) on the other hand were found to eliminate 62.63 % of glyphosate without the application of light for the same length of time, this figure rose to 87 % when 100-watt light was applied. ZONPs also decolourized 59 % Congo red after 4 h and the decolorization efficiency increased to 86 % when exposed to 30 watt light. Further, magnetic iron oxide nanoparticles (MIONPs) reduced MO by 23.81 % under 100-watt light for 120 minutes. This research demonstrates that NPs may have a future in regard to water treatment as agents which are efficient to high degree; and in part, the ZONPs are more effective in elimination of glyphosate while the IONPs may be better suited for the removal of Congo red. The evidence suggest that more attention should be paid to the characteristic of NPs, the treatment time, and the light intensity in case of employing the technology in water treatment.
